鼻声 is a noun meaning 'nasal voice' (often due to a cold or crying), while 鼻にかかった is a prenominal expression describing the quality of the voice itself, often implying an affected or unpleasant tone.
From 鼻 (nose) + に (particle) + かかった (past form of かかる, here meaning 'to be caught' or 'to be affected'). Literally 'caught in the nose', referring to a voice that resonates in the nasal cavity.
